摘要： Methods for creating and using discretized physics-based models of subsurface regions, which may contain a hydrocarbon reservoir or other subsurface feature(s). The methods may include selecting a pre-solved model, applying a mesh to the pre-solved model, defining the shape of the subsurface region to be modeled, and transforming the pre-solved model, to which the mesh has been applied, to the shape of the subsurface region. In some methods, the pre-solved model is an idealized model. In some methods, the mesh is applied to a solution of potential field lines associated with the pre-solved model, and in some methods, the solution of potential field lines is a composite solution of a plurality of solutions of potential field lines. In some methods, one or more supershapes are used to define the shape of the subsurface region. In some methods, a hyperelastic strain deformation calculation is utilized for the transforming.

摘要： Methods for creating and using space-time surrogate models of subsurface regions, such as subsurface regions containing at least one hydrocarbon formation. The created surrogate models are explicit models that may be created from implicit models, such as computationally intensive full-physics models. The space-time surrogate models are parametric with respect to preselected variables, such as space, state, and/or design variables, while also indicating responsiveness of the preselected variables with respect to time. In some embodiments, the space-time surrogate model may be parametric with respect to preselected variables as well as to time. Methods for updating and evolving models of subsurface regions are also disclosed.

摘要： Methods of predicting earth stresses in response to pore pressure changes in a hydrocarbon-bearing reservoir within a geomechanical system, include establishing physical boundaries for the geomechanical system and acquiring reservoir characteristics. Geomechanical simulations simulate the effects of changes in reservoir characteristics on stress in rock formations within the physical boundaries to determine the rock formation strength at selected nodes in the reservoir. The strength of the rock formations at the nodes is represented by an effective strain (εeff), which includes a compaction strain (εc) and out-of-plane shear strains (γ1-3, Y2-3) at a nodal point. The methods further include determining an effective strain criteria (εeffcr) from a history of well failures in the physical boundaries. The effective strain (εeffcr) at a selected nodal point is compared with the effective strain criteria (εeffcr) to determine if the effective strain (εeff) exceeds the effective strain criteria (εeffcr).
